To make source image sets suitable for serving as tiled images, significant image processing is required. This chapter provides a discussion of the image processing techniques necessary to create a tile-based GIS. It discusses algorithms for manipulating, cutting, and scaling different types of images. Several image interpolation algorithms are given with examples and discussion of the relative benefits...
Any system that uses maps must take into account three properties: datums, coordinate systems, and projections. These properties specify our model of the Earth and the way in which we specify locations upon it. In the world of geodesy there are a number of different options for each of these properties with no one “best fit” choice for all applications. While it is often not necessary to use more...
The purpose of this chapter is to present specialized techniques for tile serving that will support a wide variety of mapping tools. We will build an interface for Google Earth using the Keyhole Markup Language (KML). We will also build an Open Geospatial Consortium (OGC) Web Map Service (WMS) server.
